Add memory/file limits through prlimit and fix some issues (#4)

* use prlimit for max memory and file sizes

* use arc for rules and make examples tests

* add *_if functions to CommandExt and improve MemorySize struct

* fix tests

* disable sanitizer checks and add prlimit_std test

* capture stdout and stderr from tests

* install node

* gotta sudo apt on that thang

* safety was cringe anyways

* bump version
